What is a line of best fit?

Back

A line that best represents the data on a scatter plot, showing the trend of the data points.

Front

What does a positive association in a scatter plot indicate?

Back

As one variable increases, the other variable also increases.

What does a negative association in a scatter plot indicate?

Back

As one variable increases, the other variable decreases.

What is an outlier in a data set?

Back

A data point that differs significantly from other observations, often lying outside the overall pattern.

How do you determine the line of best fit visually?

Back

By drawing a line that minimizes the distance from all data points to the line.

Front

What does it mean if there is no relationship in a scatter plot?

Back

Changes in one variable do not affect the other variable.

Front

What is the purpose of the line of best fit?

Back

To make predictions about one variable based on the other variable.

Front

What are coordinates in a scatter plot?

Back

A pair of values (x, y) that represent the position of a point on the graph.

Front

How can you identify an outlier in a scatter plot?

Back

By looking for points that are far away from the cluster of other points.

Front

What is the significance of the slope of the line of best fit?

Back

It indicates the rate of change between the two variables.
